Pluggable reflection would be helpful not only for retargeting javadoc to reflection but also to let new language extensions reason about themselves explicitly. This need is symptomatic of the difficulty in keeping reflection in step with language features. Pluggability could avert this problem. Indeed, pluggable reflection can and should become as standard a facility as garbage collection. In the meantime, the implementation we describe here can help bring reflective facilities to new languages that lack them.
